depends on a lot of factors. If it was a current tape, no, because anyone dumb enough to make a sextape as a politician should not be elected. If it was an old sex tape, maybe, depending on the nature of the tape. Was the politician cheating If so, no, if they can't be faithful to their spouse, they won't to their constituents. If it was for money, probably not and if it was intended to be put on the internet (opposed to a leak) then no, because that might just be attention whoring.
